ABSTRACT:
The invention relates to an apparatus for rotating a suspended material handling unit comprising an elongated housing to suspend the upper end of the housing from a pivotable support, and a rotor member, having a material handling unit mounted thereto. A bearing is mounted externally of the housing between the ends of the housing so as to rotationally support the rotor member relative to the housing. A fluid operated rotary motor is mounted inside the housing and has a vertical drive shaft depending from the bottom of the housing. Drive members are operatively connected to the vertical drive shaft for rotating the rotor member and the material handling unit relative to the housing. A hydraulic swivel sleeve is mounted on the external surface of the housing unit below the bearing for rotation relative to the housing. A fluid operated motor for actuating the materials handling unit is provided as are fluid conducting members interconnecting this motor, the swivel sleeve and a source of operating fluid.
